T E N N l S N ET SPECIFICATION forming part of Letters Patent No.497,662, dated May 16, 1893.

Applicationfiled November 25, 1892. Serial No. 453,077- (No model.)

To all whom it may concern:

Be it known that I, CHARLES HENDRICKSON, a citizen of the United States,residing at New Brighton, in the county of Richmond and State of NewYork, have invented new and useful Improvements in Tennis-Nets, of whichthe following is a specification.

This invention relates to tennis nets and consists in certain novelfeatures as described and shown in the following specification, refencebeing had to the accompanying drawings in which- Figure 1, representsthe center piece of a tennis net composed of double thread loops, thesaid loops alternating with open spaces at the ends of the center piece.Fig. 2, represents the netin course of completion. Fig. 3, represents atennis net made according to the old style.

In Letters Patent No. 394,138, granted to George F. Shepard, December4,1888, a tennis net is described, the end portions of which arecomposed of single cords interlocked to form meshes, each bounded by asingle cord, while the middle portion of said net is composed ofcords'interlocked to form meshes, each bounded on all sides by twocords, forming an outer mesh and a smaller mesh just within and in theplane of the first or in other words, said tennis net is composed of endportions having single cord meshes and of a middle portion having doublecord meshes. Tennis nets of this kind have been manufactured and sold inthe United States at least for ten years last past and in order toexplain the advantage of my invention I have represented in Fig. 3atennis net of the kind described in said Patent No. 394,138. In thisfigure the letter A designates the middle portion composed of doublecord meshes and B B are the end portions composed of single cord meshes.In the process of knittinga net of this kind a device is used which istechnically called a needle but which resembles the shuttle of a loomand which contains two cords. The operative first forms the mesh 1)(Fig.3), then the meshes 19 b then the meshes b to 19 then the meshes bto b and so on and until the line of meshes b b is reached. Theoperative uses only one of the cords in his needle but when he reachesthe mesh 12", the second cord of the needle is introduced and thissecond cord is continued in forming the first two double cord meshes.in'the line b b butif the third mesh in this line is reached, which isa singlecord mesh, one-of the cords in the needle has to be cut and itsend tied by a knot to one of the meshes already formed and then theremaim it to one of the meshes already formed requires much time and theknots which appear on the net impart to the same an unsight-1yappearance. In order to overcome these disadvantages I first completethe mid-. dle portion A of my net with the double cord needle and asshownin Fig. lot the drawings this middle portion is provided at itsends with double cord meshes a a a &c., with intervening open spacess s,&c., and when the middle portion A has been finished with a double cordneedle, I take a single cord needle for the purpose of finishingthesingle cord end -portions B a portion of one of which is shown inFig. 2. In order to effect this purpose I draw the end 0 of the cord out1 of the needle and tie the same to the middle portion A at 0*. Then Ifinish the single cord mesh (Z and at the same time I form a dependingloop (1* (technically called a jocker) which is afterward used inclosing the open space 8.

By referring to Fig. 2 it will be seen that when the net is completed,the double cord meshes a a, &c.,of the middle portion A are bounded attheir junction with the single cord portion B by three cords while themesh es s s, &c., are bounded at their junction with the single cordportion B only by two cords so that when my net is completed, it can bereadily distinguished from the tennis nets heretofore known. It willalso be seen from this explanation, that I am' enabled to knit themiddle portions A composed of double cord meshes by themselves, so thatone man can devote his whole time to knitting these middle portionswhile other men are engaged in joining to said middle portions the end eV n r 497,662
